exec "rsh $plant /u1/bin/forkit '/u1/bin/zwork.pl'"

How do I use the above, which starts my process then lets my calling program
continue, to check for an error?  In this particular case, the error occurs
because zwork.pl does not exists on the maching the rsh is calling and I
need to note this error.

I tried doing this:
  exec "rsh $plant /u1/bin/forkit '/u1/bin/zwork.pl'" or excep("couldnt
exec.") but it didn't work.
